The main function of vacuum packaging is deoxygenation, which helps to prevent product spoilage. The principle is relatively simple, as product mold and spoilage are mainly caused by the activity of microorganisms, and the survival of most microorganisms (such as mold and yeast) requires oxygen. Vacuum packaging uses this principle to extract oxygen from the packaging bag and product cells, causing microorganisms to lose their living environment. Vacuum packaging can also prevent product oxidation, odor, and spoilage, while also having functions such as pressure resistance, gas blocking, and preservation, which can more effectively maintain the original value of the product in the long term.
A manufacturer has stated, "The function of a fully automatic vacuum packaging machine in the field of drugs is to tightly package drugs, isolate the entry of external air, and play a moisture-proof and anti fouling effect, which plays an important role in ensuring drug storage."
With the improvement of drug quality by the country, vacuum packaging machines have gradually become essential equipment in the pharmaceutical industry. With the continuous progress of science and technology, the rapid development of the pharmaceutical product industry, and the increasingly fierce competition in the pharmaceutical packaging equipment market. The industry believes that in the future, pharmaceutical packaging machines will cooperate with industrial automation to promote the overall level of packaging equipment improvement. The development of multifunctional and high-efficiency packaging equipment has become a trend in the industry. With the rapid development of automation technology, fully automatic vacuum packaging machines, due to their completely automated packaging process, do not require manual participation in the entire packaging process, and the packaging speed is quite fast, can bring huge production volumes to enterprises.
Some manufacturers have stated that "labor costs are rising now, and this problem will become increasingly prominent in the future. To solve the problem of the number of workers and ensure normal production, it is necessary to rely on new technologies and highly automated capabilities. The development of fully automatic vacuum packaging machines just meets the current needs." The fully automatic vacuum packaging machine bag system adopts stepper motor subdivision technology, and the controller displays Chinese characters, The heat sealer has four temperature control channels and a reliable photoelectric detection system, which can automatically print the batch number or production date. The finished product is easy to tear off and is a good helper for drug packaging.
Although the development of automation has brought new upgrades to vacuum packaging machines, the industry points out that after being fully automated, vacuum packaging machines are not able to self machine bag forming like other vertical or pillow packaging machines, and there are also limitations in their design. The existing fully automatic vacuum packaging machines have not yet achieved full automation and still belong to the category of bag feeders. The bag feeder is introduced into the system through a rotating workstation. Automatic filling and rotating multi station vacuum chamber, although the efficiency has been improved, the cost is too high and automatic bag forming has not been achieved.
Manufacturers of fully automatic vacuum packaging machines should also improve their packaging concepts from a design perspective, solving problems such as automatic bag forming, quantitative filling, vacuum sealing, and product sorting, while also avoiding simple equipment listing. Enterprises need to strengthen integration, reduce the difficulty of matching devices, and systematize devices.
